Lightspeed thru apache

Ok, after struggling getting apache/ruby to work correctly on a centos cpanel server, I had went to Mongrel. I did not like the fact that Mongrel had to be run per account. After some searching I have found litespeed.
I have a couple questions.

What I want to do is have apache handle all web traffic but Ruby accounts. I would like a straightforward easy setup and then easy config each time an account needs setup.

Any recommendations? Does Litespeed have a similar functionality to run as a proxy to apache? Is it possible to just set the proxy settings in apache httpd.conf or .htaccess and then it autoload with Litespeed running on say port 8000?

What is the best possible setup?

Also please do not ignore the questions above but if I ever decided to do away with apache completley, are there any pitfalls using litespeed with cpanel?

I think it is the best to use LiteSpeed with Cpanel directly. LiteSpeed can use the httpd.conf file generated by Cpanel, you can have your normal vhosts managed by Cpanel and have your Rails account managed via our own web admin interface as there is no equivalent configuration in Cpanel.
